Synergistic Municipal Wastewater Treatment Using a Rotating Algae Biofilm Reactor

Summary

This project addressed the challenge of expanding the bioeconomy's resource potential by creating a low-cost supply of algae biomass for bioproducts, while simultaneously integrating sustainable municipal wastewater treatment. The approach involved using a Rotating Algae Biofilm Reactor (RABR) system to cultivate microalgae in nutrient-rich anaerobic digestion effluent, thereby upcycling nitrogen and phosphorus into valuable bioproducts like biofuels, bioplastics, and biofertilizer. The project is completed, demonstrating the technical effectiveness and economic feasibility of the RABR system for both cultivating and mechanically harvesting biofilm microalgae, and showing the biodegradability of produced bioplastics while contributing to environmental protection by mitigating harmful algae blooms.
